Hi MF,
Since a few weeks the German Antarctic research station Neumayer III (
https://en.wikipedia.org/wiki/Neumayer-Station_III) is running a Red Pitaya on a wideband RX
antenna to receive/decode/upload WSPR reports on up to 8 bands simultaneously. You may have noticed them already on the WSPR map on other bands. I saw regular spots on 160m from DL statations and other countries in EU.
They seem to have quite a good satellite internet connection. So uploading WSPR spots is no problem. They also run an up to date webcam showing an image for example here:

One of the maintainers of the radio station there is Felix / DL5XL. I know him personally and, taking the idea of EA5DOM, i contacted him and asked if they want to try to receive on 630m as well. Yesterday i got an answer.
DP0GVN in IB59UH will receive WSPR(2) on 630m daily between 4...7 UTC now.
I asked them if they can extend the time to 20...07 UTC. Let's see.
So
turn on your PAs and make a first contact from your continent to Antarctica on 630m! And spread the message into other reflectors, VK could be in a favorite position.
